Jaw Pain

The left side of my jaw hurts when I open my mouth or move it side to side. It is only on the back left hand hand side where the mandible attaches to the remainder of the skull. When I go to eat a meal, the first couple times i open my mouth it is painful and then the pain decreases making me think it is a muscle of ligament problem. I went to the dentist a month ago and had no sign of cavities so I doubt it to be a dental problem. I just woke up one morning about a week ago and it was like this. Any suggestions?
